CULTlVATOR-TOOTH.

SPECIFICATION forming part of Letters Patent No. 528,603, dated November6, 1894.

Application filed November 23, 1893- Sen'al No. 491,711. (No model.)

T at whom it may concern:

Be it known that 1, CHRIS MAUL, a citizen of the United States, residingat Brockpo'rt, in the county of Monroe, in the State of New York, haveinvented certain Improvements in Cultivator-Teeth, of which thefollowing is a specification, reference being had to the accompanyingdrawings. My invention relates to certain improve- 1o ments incultivator teeth, which improvements are fully described and illustratedin the following specification and the accompanying drawings, the novelfeatures thereof being specified in the claims annexed to the :5 saidspecification.

In the accompanying drawings representing my improvements-Figure 1 is aside elevation of a set of revolving spadingteeth,the collar next theobserver being removed. Fig. 2 is a section, on the line 22, Fig. 1.Fig. 3 shows the inner surface of one of the collars. Fig. 4showstheinner surface of the opposing collar.

In the accompanying drawings A A repre- 2 5 sent a set of revolvingcultivator teeth, of the style which are now generally known as spadingteeth, projecting radially outward from a central axis, and being curvedand bent at their outer endsin any suitable manner to adapt them to thepurpose. Each tooth is formed as a separate blade, extending inwardbetween the collars B O to or nearly to the central axis, and secured inplace byalug D on one of the collars projecting through an 3 5 openingin the inner end of the blade. Be-

tween the edges of the teeth, the angular shaped lugs E project from oneof the collars to a distance corresponding with the thickness of theteeth. The lugs D are preferably made to enter recesses F in the face ofthe col lar O. In this way the collars are compelled to revolvetogether, and the blades are more firmly supported. The edges of theinner ends of the blades are beveled, on radial lines, as indicated atH, Fig. 1, so that they abut against each other, and are thus preventedfrom turning on the lugs, if the latter be made round, as shown.

Any suitable number of blades may be employed, and any suitable numberof sets of 5c blades may be connected together by a central rod J into agang or section,-the sets being separated from each other by suitablespools I, having heads at their ends adapted to engage with recesses inthe outer surfaces of the 5 5 collars, so that the sets are compelled torevolve together. These sets or gangs may be employed in any suitabletype of cultivating or spading implement,their construction being suchthat they are cheap and durable, and permit of easy repair in case ofbroken teeth. The rod J is provided with a thread and nut, so that thewhole structure isv held firmly together.

I claim- 1. The combination, with a set of, radially arranged perforatedcurved spading teeth, having their inner ends beveled to form abuttingedges, of opposing collars located on opposite sides of the teeth, oneof said collars being provided with integral projecting lugs adapted toengage between the sides of adjacent teeth, and one of the said collarsbeing provided with integral lugs adapted to engage in the perforationsof the teeth, substantially as described.

2. The combination, with a set of radially arranged perforated spadingteeth, having their inner ends beveled on the edges, of opposing collarslocated on opposite sides of the teeth, one of the said collars 'beingprovided with integral lugs adapted'to engage in the perforations oftheteeth, and the other with recesses adapted to receive the ends of thelugs, substantially as described.
